Britney Welcomes Home Sean Preston

Britney Spears and Kevin Federline's new bundle of joy, Sean Preston Federline, is now safe at home in his new Malibu nursery, PEOPLE reports in its latest issue.

The magazine, on newsstands Friday, reveals more new details about Britney's delivery, as Spears and Federline showed up at Santa Monica UCLA Medical Center early Sept. 14 with Spears's mom, Lynn, and sister Jamie in tow.

Originally, Britney had been scheduled for a C-section the next day, but the surgery was moved up after she began experiencing early contractions. With her husband at her side, Spears, 23, was wheeled into the operating room, and both parents were crying when the baby was born. Sean Preston weighed in at 6 lbs. 11 oz.

Federline, 27, who held his wife's hand throughout the operation, "was very affectionate toward her," says a source. After the delivery, the new mother was moved to the maternity ward's VIP suite, where, the source also says, "The baby never once left her side."

Now home in Malibu, Sean has a brand-new nursery in Mom and Dad's just-renovated, 9,000-sq.-ft. crib. And he already has a substantial wardrobe to supplement the gifts Britney got at her Aug. 6 Moroccan-themed baby shower.

On one visit to Kitson Kids on Aug. 2, "Britney was completely in baby mode," owner Fraser Ross tells PEOPLE.

Among her purchases: onesies and a cashmere sweater with a faux Mommy tattoo on the sleeve – to go with such gifts from friends and family as a pair of Yo My Booties angora booties, a tunic and a hat from an assistant and some T-shirts from a pal.
